I've been searching for days on ways to fix this,
but finally decided to ask
people who may be able to help. ;-) Hardware: Compaq OEM - AMD K6-2 350, VIA MVP3 chipset. I know this combo wasn't very stable or high performing, but I can't afford the money to build another decent looking box. Leadtek Winfast 2000XP Software: XawTV 3.85 Kernel 2.4.19 w/ BTTV 0.7.105 XFree 4.2.99.4 latest versions of transcode, ffmpeg, NuppleVideo, etc capturing programs. I can see TV fine when XawTV is set to overlay mode. When it is not though, I get no picture. This unfortunately means that captures don't work - I get a perfectly white image. In XawTV, I get a black screen. The difference makes me wonder if it is some configuration issue, but all I change is the capture mode and the results change. After realizing that only overlay mode worked, I went to look at the V4L docs, and saw that for overlay mode you can specify the base address of the area to be written to. I know that this is not the point of an overlay, but can I allocate an area of memory and pass that pointer into the driver? I don't care how I get an image into RAM where I can manipulate it, but screenscraping can't be the best solution (and it requires significantly more work in terms of handling the image). Has anyone else experienced this problem? Is there a solution? I can't get BTTV 0.9.x to compile, nor the V4L2 drivers, so I can't test those out. Thanks, Andy |
